I don't. Oh, I'll spend some down time learning rather than spending all of it here, but I don't expect formal training, especially if I am asked to jump in to some project quickly. In fact, most formal training I have been exposed to outside of school has been horrible and useless; I actively avoid them.
I expect employers to give me paid time to learn stuff they require me to use at work, but if it is something unrelated to the company I am not expecting them to give that time.
